The overall aim of MVDC-ERS is to investigate the next generation railway electrification systems, DC power electronic traction transformers and technologies for integrating renewable sources, to challenge the traditional rail approach to develop innovative and breakthrough technological concepts.
Objectives
- To introduce new high-efficiency topologies of power conversion systems to convert medium-voltage AC power into medium-voltage DC power with the capability of limiting the short circuit current.
- To introduce high-power density topologies of power converters for on-board DC transformers.
- To investigate the impact of the forthcoming wide band-gap semiconductor devices in terms of efficiency and voltage level for the converters of the feeder stations and in terms of weight and volume for the traction converters.
- To understand how the new railway electrification system should be controlled and protected when renewable power sources are integrated.
- To understand how on-board energy storage can be exploited and how it can optimise the operations of the network.
- To work with industrial stakeholders to investigate the marketability of the new electrification system and trains.
